SPECIFICATION forming part of Letters latent N0. 602,201, dated April 12, 1898. Application filed August 7,1895. Serial No. 647,494. (No model.)

My invention relates to means for operating the dashers of vibratory churns, and has for its object more particularly to provide certain improvements in the constructionldisclosed in Letters Patent granted May 29, 1894,

to John M. Hughes, No. 520,566, whereby the mechanism for supporting the operatinglever is materially simplified and strengthened. This object I accomplish in the manner and by the means hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of my improved device. Fig. 2 is an enlarged detail View of the point of connection between the shaft-section and its supporting-bracket.

In the said drawings the reference-numeral 1 denotes the churn-body, provided with any suitable vibratory dasher 2, carried by a dasher-shaft 3, the upper end of. which is squared to engage into a socket 4, that is detachably engaged with the shaft-section 5 by a suitable thumb-nut or pin, as shown.

The shaft-section 5 is spirally threaded, as shown, to engage with the interior threads of a vertically-reoiprocatory bur or nut 6, said nut being provided with trunnions 7, adapted to be engaged by suitable apertures in the bifurcated inner end of the operating-lever 8.

The shaft-section 5 is supported at its upper and lower ends by a substantially U- shaped bracket 9, fixed to the wall or other support, said bracket being provided with 'a' horizontal slot 10, through which is loosely passed a bolt or roller 11, engaged with the extreme inner bifurcated ends of the operating-lever 8.

In order to provide for the removal of the shaft-section 8 from its supporting-bracket 9, I form the upper bearing for said shaft-section witha removable section 12, normally retained in position by a thumb-nut 13.

From the above description the operation of my improved construction will be understood to be as follows: lhe parts being connected together and the outer end of the opcrating-lever 8 vertically reciprocated, a rapid vibration will be imparted to the shaft-section 5 through the bur or nut 6 and from said shaft-section to the dasher-shaft 2 and dasher 1. The necessary play is permitted to the inner end of the lever 8 through its engagement with the slot 10, and at the same time the absence of any pivotal parts, as in the patented construction hereinbefore referred to, affords a stronger and much simpler construction that will stand any amount of wear. Moreover, by bifurcating the'inner end of the lever 8 and making these bifurcated ends slightlyresilient the same can be readily engaged with and disengaged from the trunnions 7 of the bur 0r nut 6 and retained in operative position by means of the bolt 11, as will be readily understood. To disengage the operating mechanism from the dasher-shaft 3, it is only necessary to loosen the thumbnut on the socket 4 and remove the section 12, when the shaft-section 5 may be drawn up out of engagement with the socket 4.

Having thus described my, invention, what I claim as new, and desire to secure by Letters Patent, is-

- 1'. In a churn-operating mechanism, the combination with the churn-body, a vibratory dasher therein, a dasher-shaft therefor, a spirally threaded shaft-section engaged with said dasher-shaft, a bracket supporting said shaft-section, and an interiorly-threaded bur or nut vertically movable on said shaft-section, of an operating-lever engaged intermediate its ends with said bur or nut and having its inner end horizontally movable in a.

slot in the supporting-bracket, substantially as set forth. x

2. In a churn-operating mechanism, the combination with the churn-body, a vibratory dasher therein, a dasher-shaft therefor, a spirally-threaded shaft-section engaged with said dasher-shaft, a bracket supporting said shaft-section, and an interiorly-threaded bur or nut vertically movable on said shaft-section, of an operating-lever having its inner end bifurcated and slightly resilient, said bi- In testimony whereof I have hereunto set furcated portion adapted to engage with trunmy hand in the presence of two Witnesses. nions on said bur or nut, and a bolt engaged WILLIAM GARFORTH STONE with the extreme inner ends of the bifurcated 5 lever and movable horizontally in a slot in Witnesses:
